I'm pretty sure Al Gore invented television. Are you sure this article is reliable?
Philp did indeed invent Television. RCA even went to court over it, saying that their guy (Zarnoff) invented it. Z got all the publicity, but eventually it came out that Farnsworth was the man. An unheralded genius. That guy could do things with vacuum tubes that were way ahead of his time. Some say he was on his way to developing a form of fusion reaction.
